Dear SBS collaborators,

   Attached below is a proposed abstract for submission for the DNP 
meeting. Please let me know before Monday if you have any suggestions or 
concerns.

 		Thanks,

A high efficiency neutron/proton detector for high-Q$^2$ form factor
measurements

Brian Quinn for the Super Bigbite Spectrometer collaboration

A hadron calorimeter for use with the Super Bigbite Spectrometer in
Hall A at Jefferson Lab is in the final stages of design and
simulation.  It is a {\em shashlik} calorimeter with iron and
scintillator layers with wavelength shifter readout.  It has been
designed to give excellent spatial and timing resolution.  Its stable
high efficiency for both neutrons and protons will make it a valuable
tool for high-Q$^2$ nucleon-coincidence measurements of nucleon form
factors.  The design will be presented along with results of detailed
simulation.
